1. Equipment preparation
1. Check whether the equipment required for the feed extruder is complete, and whether there are any abnormalities in the electrical system, mechanical system, etc. of the equipment.
2. Clean and check whether there are foreign objects in the feed extruder body and accessories, especially the guide wheel, swing arm and other parts that are prone to damage, organize the feed storage car, clean the batching equipment and pipelines, etc.
2. Preparation before operation
1. Check whether the content of feed and moisture meets the requirements to ensure accurate batching.
2. Prepare the tools, operating table, sieve bucket, etc. required for operation.
3. Start-up operation

1. Operate according to the equipment manual, turn on the power supply and gas source.
2. Open the steam valve, adjust to the appropriate amount of steam, and adjust the value of the temperature controller.
3. Switch to the clinker mode, move the swing arm by the robot hand to check the flow rate, and ensure that the feed flow rate is normal.
4. Adjust the feeding amount and discharge amount.
Precautions during production
1. Do not increase the amount of feed excessively during production to prevent excessive dust.
2. During production, regularly clean the guide wheel, swing arm and other parts that are prone to damage to ensure the normal operation of the machine.
3. During operation, protective gloves and work clothes must be worn to avoid personal injury.
4. All personnel must have relevant knowledge of operating the feed extruder and cannot operate it at will.
5. During production, pay attention to the storage of combustible items to avoid fire sources.
